一直报IllegalAccessError的错误，怎么解决呢

我的错误信息如下

Start with the stack trace at PersonalDataActivity.java:111 and compare the reported PersonalDataActivity_CF.initView() access with the Android Instant Run dex location. Reproduce the failure in the affected Android setup, then identify a confirmed cause and document a verifiable resolution for the IllegalAccessError.
